My bad, I mean to type the choice should have been of 25^2(root2) instead of 25^(root2) .
Can someone please explain the property of exponent for this question?
Maybe it would be easier with another number
Lets say 4^sqrt 4
this would = 16
now let's say (4^sqrt4)^2 = 256
remember 5^2 * 5^3 = 5^5 because we add the exponents
so from the above example we would get 4^(2*sqrt 4)
that would in turn = 16 ^ sqrt 4 (if you wanted to solve that would equal 16*16) or 256 same as above
the point is that you add the square root not square the square root and keep the base number the same
